I all whom it mayconcern.-

Be it known that 1, JOSEPH IMLER. a citizen of the United States, residing at Garrett, in the county of De Kalb and State of Indiana,

have invented a new and useful Improved Machine for Driving \Vell-Tubes, of which the following is a specification.

My invention relates to an improved machine for driving well-tubes.

The objects of my improvements are to pro vide in a portable machine adapted to be run with steam-power novel means i'orreciprocating the drill and hammer for s'inkinga tubular well, means for raising and lowering the tube 1 and the drill, and means for forcing water into the same during the operation of drilling, all as hereinafter fully described.

The accompanying drawings illustrate my invention. Figurelisaside elevation; Fig. 2, a partial elevation of the side opposite Fig. 1. Fig. 3 is a frontelevation. Fig. 4:, a transverse vertical section at r,Fig. 1; Fig. 5, a plan below the line 3 ,Fig. 1; Fig. 6, an enlarged detail.

A is a platform or bed-frame mounted 'on a suitable carrying-wheels, and having erected thereon the derrick B and machine-frame 0.

On frame Care mounted in suit-ablejournalhearings the drivingshaft 0, crank-shalt b, 0 Windless 0, pumpshatt d, and windlasses e and f. On the driving-shaft aaresecured the belt-pulleys g and h and pinionsi and j. On the crank of shaft b is a grooved friction-pulley, 7c, and on the outer end a belt-pulley, l. A pair of gear-wheels, D and E, are mounted on shaft 1), D turning loosely and having a longitudinal movement on theshaft, and E mounted so as to turn therewith, but having a limited longitudinal movement thereon, which movement is effected by means of the forked levers 1 and 2. \Vindlasscis provided with a gear-wheel, H, which intermeshes with wheel D, and has also a brake-wheel, m, which is engaged by the brake it, operated by a lever, 5 0, pivoted to frame 0. Windlass f has a gear- Wheel, I, with which gear-wheel E intermeshes, and a brake-wheel, J,which is engaged by the brake p. WVindlass 8 has a gear-wheel, 7, which meshes with wheel I on windlassf.

1? is a force-p11 mp, mounted on the bed-frame l-beside frame Oand operated bya. pitman connected with wheel, r on shaft d, which is driven by belt 8, passing over pulley l on the crank-shaft.

\(V is the well-tube, which is sustained and guided in avertical position by.cross-timbers of the derrick, tand u, through which it passes.

X is the drill-rod,which passes through the drivingcap Y on the well-tube. On the upper end of the drill-rod is a swivel-coupling, to Q. having a branch pipe, '0, which is connected with the discharge of the force-pump P by a hose, R. In the driving-eap is a branch pipe, w, to which is connected the hose a.

S is a heavy casting of iron clamped upon the drill-rod, for the purpose of adding to the weight of the drill, and also to serve as a hammer for driving the well-tube. The drillrod is hollow, and the purpose of pump P is to force water through the drillrodand drill to the bottom of the welltube, and thence up between the inside of the well-tube, and outside of the drill-rod, till it passes off through the hose 0:. U

The construction, arrangement, and operation of the drill, drill-rod, and weight I reserve to form the subject-matter of a separate application for a patent, and they therefore are not more particularly described here. A rope, 1 is fastened to the swivel Q on the drill-rod and is passed upward over a pulley, z,thence.downward over the grooved pulley lo, and thence backward to Windlass c, where it is made fast. Said rope y is for the purpose of raising and lowering the drill, and the purpose of the crank-shaft b is to give the drill, by means of rope y, a reciprocating motion, as hereinafter explained. A second rope, 3, passes from windlassf over a pulley, 9c 4., and is shown as secured to one side of the derrick-frame. The purpose of said rope and windlassf is to raise the well-tube when necessary. A third rope, 5, passes from windlass 6 over a pulley, 6, and is shown as se- 5 cured to the rim of one of thecarrying-wheels. The purpose of said rope and Windlass is to raise and lower a sand-purnp within the welltube, when necessary.

The operation of my machine is as follows:

Crank-shaft b is turned so as to bring the crank near Windlass c. The Windlass is then turned by means of the hand-crank 9. and rope y drawn taut. Gear-wheels Dand E are now slipped inward on shaft b, so as to be out of mesh with other gear-wheels, but remaining in mesh with the pinions on the drivingshaft, and power is applied to revolve the driving-shaft a. Gear-wheel E being secured to the crank-shaft so as to turn therewith, the crank-shaft is revolved, and as the crank recedes from the Windlass a bight is thereby formed in rope y, thus drawing the drill upward. When pulleyk has passed its farthest point from the Windlass, the bight of the rope is released and the drill suddenly falls, the operation being repeated ateach revolution of the crank shaft. The operator controls the turning of windlass c by means of the brake-levcr 0', so that as the drill falls a sufficient length of rope is drawn from the windlass to compensate for the penetration of the drill. \Vhen the operator desires to raise the drill out of the tube, wheel D is thrown, by means of lever 1, into engagement with wheel H on the Windlass c, and the Windlass is thereby revolved. When the tube is to be raised, the free end of rope 3 is secured to the tube and wheel E is thrown, by means oflever2, into engagement with wheel I, and Windlass f is turned so as to wind up rope 3, thereby raising the tube. The tube when raised issustained by an automatic clamp, Fig. 6.

10 is a casting resting on the lower crosspiece of the derrickfraine. Said casting has a central tubular portion in which the tube fits so as to slide easily. In opposite sides of said tubular portion are pivoted a pair of cam-shaped dogs, 11 12. Said dogs have serrated surfaces which rest against opposite sides of the tube, and the arrangement is such that when the tube is raised it slides easily between the dogs, but a downward movement of the tube engages the serrations of the dogs and tends to force the dogs toward each other, thus securely holding the tube. When the tube is to be lowered, wheel E is thrown out of gear and the movement of the Windlass is controlled by means of brake 1). As the operation of drillingproceeds pump P is operated,and having, by means of pipe 8, been connected with a water-supply, water is forced into the drillrod and well-tube, as before explained, the purpose being to carry away the earth excavated by the drill. A portable and compact machine is thus provided by means of which tubular wells may be rapidly sunk.

I claim as my invention- 1. In a machine'for sinking well-tubes, the derrick, the drill-rod, Windlass c, crank-shaft I), pulley lo, and rope y, all combined and arranged to cooperate in the manner and for the purpose specified.

2. In a machine for sinking well-tubes, the combination, with the derrick, the tube, the rod arranged to slide vertically within the tube, the Windlass c, the crankshaft b, and the rope y, of the brake arranged to control the movement of the Windlass, substantially as and for the purpose specified.

3. In a machine for sinking well-tubes, the combination, with the bed-frame, the derrick erected thereon, the machineframe, windlasses c and f, gear-wheels H and I, and drivingshaft, a, having pinionsiand j, of shaft 0, gear wheels D and E, and levers l and 2, whereby either or both of said windlasses may be operated from the driving shaft, substantially as set forth.

4. In a machine for sinking well-tubes, the combination, with a bedirame, a derrick erected on said frame, a well-tube arranged vertically under said derrick, and a tubular drill-rod arranged to slide vertically in said tube, of a force-pump mounted on the bedframe, a hose connecting the clischarge'pipe of said pump with the drill-rod, and means, substantially as shown and described, for re ciprocating the drill-rod and operating the pump simultaneously, all arranged to co operate substantially as and for the purpose specified.

JOSEPH IMLER.
